Intracerebral CSF collection mimicking cerebral abscess in a patient suffering from cryptococcal meningitis.

We report a case of a large intracerebral CSF collection formed along the course of the catheter of an ommaya-type reservoir (Medtronic 12 mm), implanted in a patient suffered from cryptococcal meningitis in the frame of CLL. This collection was at first diagnosed as intracerebral abscess but emergency craniotomy proves clear CSF collection with no signs of infection. We describe the case and we discuss the issue of CSF pressure pathophysiology and changes in flow dynamics, to patients with cryptococcal meningitis.
